No. 13/780,539 filed on Feb. 28, 2013, which claims priority to Chinese Application No. 201210050728.6 filed on Feb. 29, 2012, Chinese Application No. 201210322689.0 filed on Sep. 3, 2012, and Chinese Application No. 201210545973.4 filed on Dec. 14, 2012; the entire contents of each are incorporated herein by reference.

The present invention relates to the field of display technology, in particular, relates to an operation mode switching method and an electronic device.

BACKGROUND

With the development of the electronics industry, electronic devices are becoming increasingly popular, people have invented a transparent screen (i.e., a screen, comprising a display unit with a light-transmittance lower than preset). A major highlight of a transparent screen is that, users not only can watch the content displayed on the screen, but also can see the area obscured by the transparent screen through the transparent screen, and people standing in front and back side of the transparent screen all can watch the contents on the display.

By way of example, for a spectacle-type electronic device, a user can directly wear it on eyes and watch content displayed on the lens-screen; therefore, it is convenient in use and is good in user experience; however, in the prior art, the transparency of the lens-screen of a spectacle-type electronic device is non-adjustable, and the transparency is low as manufactured; thus, when the user needs to see the surroundings, that is, needs to see the real world, he needs to take off this spectacle-type electronic device, such frequent takeoff-and-wear causes inconvenience to the user. Also, when using a phone or other electronic device containing a transparent screen, a user may not see clearly a corresponding picture displayed on the screen, thus the display effect of the electronic device is reduced. In addition, in the case of adjusting parameters of the touch screen, such as luminance, transparency, etc., typically, a user needs to find a settings menu in the menus, open the setting menu, and further in the setup menu, find corresponding parameter adjustment buttons, and then perform adjustment. Such gesture operations are rather tedious, and do not comply with custom of users, thereby resulting in poor user experience.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

An embodiment of the present invention provides an operation mode switching method, applied in an electronic device; the electronic device is, for example, a mobile phone, a tablet PC, a spectacle-type electronic device, or a handheld game console, or other electronic devices. The electronic device has a first operation mode and a second operation mode, and the electronic device further comprises a detecting member; with reference to FIG. 1, FIG. 1 is a flowchart of an operation mode switching method in an embodiment of the present invention, the method comprises:

Step 101: Detecting a movement of a user's eyeball by the detecting member;

Step 102: According to the movement of the user's eyeball, judging whether or not the operation mode of the electronic device needs to be switched;

Step 103: If YES, then, according to the movement of the eyeball, switching the electronic device between the first operation mode and the second operation mode.

In order to more clearly explain the technical solutions of the present invention, hereinafter, specific examples will be described in detail.

In a first embodiment, for example, when the electronic device is a spectacle-type electronic device; the spectacle-type electronic device comprises a lens and a structural member, such as a frame; the structural member facilitates a user to wear the spectacle-type electronic device on his eyes, while the detecting member, such as a camera provided on the structural member, facilitates detecting a movement of the user's eyeball; in this embodiment, for example, the lens displays an indicative mark thereon, so that when it is detected that the movement of the user is to look at the indicative mark, i.e. the user's sight line focuses on the indicative mark, it can be determined that the operation mode of the electronic device needs to be switched; the operation modes are, for example, a 2D mode and a 3D mode, alternatively, a real scene mode and a terminal scene mode.

Further, when a user's sight line focuses on the indicative mark, it can represent that the user's pupillary distance reaches a predefined value, thereby it can be determined which operation mode of the electronic device is to be switched, for example, when the first operation mode is a real scene mode and the second operation mode is a terminal scene mode, a small pupillary distance indicates that the eyes watches a close place, then the electronic device needs to be switched to the second operation mode; a large pupillary distance indicates watching a distant place, then the electronic device needs to be switched to the first operation mode. In this embodiment, the operation mode of the electronic device is switched by adjusting the transparency of the lens, which specifically is when the operation mode of the spectacle-type electronic device needs to be switched to the first operation mode, the transparency of the lens is adjusted higher, so that it is easy for the user to see surroundings, i.e., the real scene; when the operation mode of the spectacle-type electronic device needs to be switched to the second operation mode, the transparency of the lens is adjusted lower, so that it is easy for the user to see contents on the lens; in this way, it can avoid frequent takeoff-and-wear of the spectacle-type electronic device for a user.

In another embodiment, the operation mode of the spectacle-type electronic device is switched by partitioning the lens, for example, when the spectacle-type electronic device is in a first operation mode, and the focus of the user's sight line is on the indicative mark, this indicates that the operation mode of the spectacle-type electronic device needs to be switched to the second operation mode, and this can be accomplished by adjusting the transparency of the lens in partitions, for example, the transparency of the upper half of the lens is adjusted higher, and the transparency of the lower half of the lens is adjusted lower or remained unchanged, so that the user can directly view a real scene from the upper half of the lens, also can watch the content displayed on the lens through the lower half of the lens.

In another embodiment, the lens does not require any indicative mark, but only the detecting member is required to detect changes in the user's pupillary distance, such as calculating the pupillary distance; when the pupillary distance is less than a predefined value, it indicates that the user needs to see the content on the lens, whereas when the pupillary distance is greater than the predefined value, it indicates that the user needs to see the surrounding environment; for example, when the first operation mode is a real scene mode and the second operation mode is a terminal scene mode, a small pupillary distance indicates that the eyes watches a close place, then the electronic device needs to be switched to the second operation mode, whereas a large pupillary distance indicates watching a distant place, then the electronic device needs to be switched to the first operation mode. In this embodiment, the operation mode of the spectacle-type electronic device can be switched by adjusting the transparency of the lens, which specifically is when the operation mode of the spectacle-type electronic device needs to be switched to the first operation mode, the transparency of the lens is adjusted higher, so that it is easy for the user to see surroundings, i.e., the real scene; when the operation mode of the spectacle-type electronic device needs to be switched to the second operation mode, the transparency of the lens is adjusted lower, so that it is easy for the user to see contents on the lens; in this way, it can avoid frequent takeoff-and-wear of the spectacle-type electronic device for a user. Certainly, it is also possible to switch the operation mode of the electronic device by partitioning the lens, and this method has been explained in the foregoing description, which is therefore not specifically described here.

In another embodiment, the detection member does not need to calculate a pupillary distance, but only the movement of a user's eyeball is required to be detected, to determine whether the user's viewpoint is inside the contents of the lens or outside the contents; when the user's viewpoint detected is inside the content, the operation mode of the spectacle-type electronic device is switched to the terminal scene mode, whereas when the user's viewpoint detected is outside the content, the operation mode of the spectacle-type electronic device is switched to the real scene mode; also, it is possible to switch the operation mode of the spectacle-type electronic device by adjusting the transparency of the lens or by partitioning the lens, and these methods has been explained in the foregoing description, which are therefore not specifically described here.

In another embodiment, when the first operation mode is a 2D mode and the second operation mode is a 3D mode, the operation mode of the electronic device can be switched by adjusting the display mode of the display unit of the electronic device; for example, when the movement of a user's eye is to look at the indicative mark on the lens, the 3D mode is switched to the 2D mode, alternatively, for example, when the user's pupillary distance detected becomes small to a predefined value, the 2D mode is switched to the 3D mode; this embodiment is different from the aforementioned embodiments in that this embodiment involves different operation modes and a different switching mode (switching by adjustment the display mode of the lens); with the foregoing description of the above embodiments, the skilled in the art can clearly understand the method in this embodiment, which are therefore not specifically described here.

Another embodiment of the present invention further provides an electronic device; the electronic device has a first operation mode and a second operation mode; with reference to FIG. 2, FIG. 2 is a functional block diagram of the electronic device in this embodiment, and in FIG. 2, only the part associated with the invention is shown; the electronic device may also comprise other functional modules, such as a display unit and a input apparatus, etc. The electronic device comprises a detecting member 201, used for detecting a movement of a user's eyeball; and a processing unit 202, used for according to the movement of the user eyeball, judging whether or not the operation mode of the electronic device needs to be switched; If YES, then, according to the movement of the eyeball, the processing unit 202 switches the electronic device between the first operation mode and the second operation mode.

The detecting member 201 is, for example, a camera or other measurement instrument for measuring a movement of eyes, e.g. a centrometer, and the like.

In an embodiment, for example, when the electronic device is a spectacle-type electronic device, the spectacle-type electronic device comprises a lens and a structural member, such as a frame; the structural member facilitates a user to wear the spectacle-type electronic device on his eyes, while the detecting member, such as a camera provided on the structural member, facilitates detecting a movement of the user's eyeball

Further, the lens displays an indicative mark thereon, so that when it is detected that the movement of the user is to look at the indicative mark, i.e. the user's sight line focuses on the indicative mark, it can be determined that the operation mode of the electronic device needs to be switched; the operation modes are, for example, a 2D mode and a 3D mode, alternatively, a real scene mode and a terminal scene mode.

In a further embodiment, the lens is a lens with variable transparency, so that when the first operation mode is a real scene mode and the second operation mode is a terminal scene mode, the operation mode of the spectacle-type electronic device can be switched by adjusting the transparency of the lens, which specifically is when the operation mode of the spectacle-type electronic device needs to be switched to the first operation mode, the transparency of the lens is adjusted higher, so that it is easy for the user to see surroundings, i.e., the real scene; when the operation mode of the spectacle-type electronic device needs to be switched to the second operation mode, the transparency of the lens is adjusted lower, so that it is easy for the user to see contents on the lens; in this way, it can avoid frequent takeoff-and-wear of the spectacle-type electronic device for a user.

In another embodiment, for example, when the spectacle-type electronic device is in a first operation mode, and it is determined that the operation mode of the spectacle-type electronic device needs to be switched to the second operation mode, and this can be accomplished by adjusting the transparency of the lens in partitions, for example, the transparency of the upper half of the lens is adjusted higher, and the transparency of the lower half of the lens is adjusted lower or remained unchanged, so that the user can directly view a real scene from the upper half of the lens, also can watch the content displayed on the lens through the lower half of the lens.

In another embodiment, the electronic device further comprises a display unit, and the processing unit comprises a display mode switching unit; and when the first operation mode is a 2D mode and the second operation mode is a 3D mode, the operation mode of the electronic device can be switched by adjusting the display mode of the display unit, for example, when the movement of a user's eye is to look at the indicative mark on the lens, the 3D mode is switched to the 2D mode, alternatively, for example, when the user's pupillary distance detected becomes small to a predefined value, the 2D mode is switched to the 3D mode.

In the above embodiments, when the electronic device is a spectacle-type electronic device, and when the second mode is a terminal scene mode, the user is viewing the content on the lenses of the spectacle-type electronic device; the content seen by the user may be directly displayed on the lenses, also may be a virtual display in the space, which is in a certain distance from the eyes of the user, so that the user will watch more comfortable; below, with reference to the drawings, preferred embodiments of the present invention will be described in detail. It should be noted that, in this specification and the drawings, essentially same steps and elements are represented with same reference numerals, and repeated explanation of these steps and elements will be omitted.

In the following embodiments of the present invention, FIG. 3 shows an exemplary block diagram of a spectacle-type electronic device 300 in accordance with an embodiment of the present invention. As shown in FIG. 3, the spectacle-type electronic device 300 comprises an image processing unit 310, a first display unit 320, a first optical system 330 and a first viewing window 340.

The image processing unit 310 can provide a first image. The first image is, for example, pictures, video images or texts, a combination of images, texts and pictures, etc. The image processing unit 310 may be a central processing unit (e.g. CPU) of the spectacle-type electronic device. Alternatively, it may be an image processing unit provided physically- or logically-independent.

The first display unit 320 can display the first image provided by the image processing unit 310. According to one example of the present invention, the first display unit 320 may be the micro display unit having a size less than the size of the screen of an existing electronic device. In the embodiment of the present invention, the size of the first display unit 320 is consistent with the size of the lens of the spectacle-type electronic device. The dimension of the lens matches the standard size of human eyes. In addition, according to another embodiment of the present invention, the first display unit 320 has a relatively high resolution. Specifically, the resolution of the screen of the first display unit 320 may be higher than the resolution of the screen of an existing electronic device. For example, the first display unit 320 may comply with the standard resolution of an HD or full-HD.

The first optical system 330 can receive the light emitted from the first display unit 320, and convert the optical path of the light emitted from the first display unit 320, to form a first enlarged virtual image, wherein the length of the optical path between the first optical system 330 and the first display unit 320 is smaller than the focal length of the first optical system. That is, the first optical system 330 has a positive refractivity. The magnification of the first optical system 330 may be preset. Alternatively, the first optical system 330 may comprise a first adjustment member to adjust the magnification of the first optical system 330, which will be described in detail later. The area of the first enlarged virtual image is greater than the area of the display region of the first display unit.

According to an example of the present invention, the first optical system 330 at least comprises a lens assembly having a positive refractivity. FIG. 4A is a schematic diagram showing a lens assembly in accordance with an example of the present invention. As shown in FIG. 2, the lens assembly may comprise a convex lens 210. The convex lens 210 can receive the light emitted from the first display unit 320, and convert the optical path of the light emitted from the first display unit 320, to form a first enlarged virtual image 220.

Although in FIG. 4A, the description is given, with one light line as an example, on converting the optical path of the light emitted from the first display unit 320; but it should be noted that, the light emitted from the first display unit 320 is actually a group of light rays constituted by a plurality of light rays, and the optical path of the group of light rays is converted through the lens 410, to form an enlarged virtual image 420.

In addition, in order to reduce aberrations and avoid the interference of imaging caused by dispersion, and give user better visual experience, a plurality of lenses including concave and convex lens may be used to form a lens assembly. As described above, the lens assembly formed by the plurality of lenses has a positive refractivity, i.e., it can be equivalent to a convex lens. FIG. 4B is a schematic diagram showing another exemplary lens assembly according to the present invention. As shown in FIG. 4B, the lens assembly may comprise a single-convex lens 420, a single-convex lens 430 and a concave-convex lens 440.

The image processing unit 310, the first display unit 320 and the first optical system 330 may be provided in the interior of the spectacle-type electronic device 100. The first viewing window 340 may be provided on a first outer surface of the spectacle-type electronic device, so that when a user wears the spectacle type electronic device, the first viewing window 340 faces the user's eyes. The user can view through the first optical system to see the first enlarged virtual image. According to an example of the present invention, the size of the first viewing window 340 corresponds to the size of human eyes; preferably, the first viewing window 340 may be consistent with the size of the lens of the spectacle-type electronic device.

According to an example of the present invention, in the spectacle-type electronic device, the first display unit 320 is provided at one side of the first optical system 330, and the first optical system 330 allows the user standing at the other side of the optical system 330 opposite to the first display unit 320 to watch the first enlarged virtual image.

With the spectacles-type electronic device provided by the embodiment of the present invention, the size of the image that a user can watch is not restrained by the size of the lens (i.e. screen) itself of the spectacle-type electronic device; instead, the user can view through the spectacle-type electronic device to see a larger size of displayed image. In other words, when the user wears the spectacle-type electronic device, the size of the image that he sees is larger than the size of the lens (i.e., the size of the screen) of the spectacle-type electronic device, and at the same time, the distance of the displayed image that he sees is greater than the distance from his eyes to the lenses (the distance when the spectacle-type electronic device is worn).

Specifically, in one embodiment, the display processing method to determine whether the first gesture operation is formed by the continuous curve trajectory, which is formed by coming and going between a first sliding direction and a second sliding direction. The number of the touch point may be one, or can be multiple. That is, the display processing method to determine whether the first gesture operation is similar to the so-called back and forth gesture, and the user can use a pointing (e.g., finger) to make the gesture, or can be make the same gesture using a plurality of pointing objects (for example, multi-fingers).

In another embodiment, the display processing method to determine whether the first gesture operation is formed of the touch point trajectory by several times in the same sliding direction of the sliding piece in the predetermined time interval, the locus which is formed in the track. For example, the sliding direction may be an arbitrarily set direction. The number of the touch point may be one, or can be multiple. That is, the display processing method to determine whether the first gesture operation is similar to the so-called back and forth gesture, and the user can use a pointing (e.g., finger) to make the gesture, or can be make the same gesture using a plurality of pointing objects (for example, multi-fingers).

Of course, the above embodiments are only examples. One skilled in the art can understand that the display processing method of an embodiment of the present invention can set other criterion as the first condition. Alternatively, the first condition corresponding to the trajectory is formed by trajectory which conforms to the user's habit.

Next, when the first gesture operation does not satisfy the first condition, the display processing method ends.

On the other hand, when the first gesture operation satisfies the first condition, the display processing method proceeds to step 1503.

At step 1503, the display processing method obtains a first adjustment parameter. Wherein the first adjustment parameter is used to adjust the parameters of the image in a first adjustment direction. The adjustment parameters is, for example, the electronic device's transparency, brightness, etc. The first direction of adjustment, for example, is one of the increasing direction and the decreasing direction. Here, the direction for increasing is assumed. For example, in the case of brightness, the first adjustment parameter may be a brightness increase amount.

In one embodiment, the display processing method, according to the first gesture operation, obtains a fixed first adjustment parameter. I.e., in the above case, for example, whatever the track of the first gesture operation is, as long as it satisfies the first condition, the display processing method obtains identical first adjustment parameters.

In another embodiment, the first adjustment parameters may be variable. Specifically, the display processing method, according to the first gesture operation, determines the size of the first adjustment parameter.

More specifically, in the case of the judgment formed by the touch point in the operation in the first gesture trajectory is a continuous curve trajectory is formed on the first sliding direction, and with the first sliding direction, different from the second sliding direction of roundtrip. Next, the display processing method can be continuous curve track back and forth in the first sliding direction, and the second sliding direction by calculating the round-trip times, to determine the corresponding first adjustment parameter. For example, the display processing method may be designed such that the number of reciprocations more the larger the first adjustment parameter.

As another example, in the judgment of the first gesture operation is formed by the touch-point trajectory is case several times in the same sliding direction, the sliding piece trajectory of the track formed by a predetermined time interval, the display processing The method can determine by calculating the number of segments of the track multi-piece track corresponding to a first adjustment parameter. For example, the display processing method may be designed such that the number of segments, the first adjustment parameter bigger.

Thereafter, in step 1504, the display processing method obtains the image information of the displayed image. The image information is required to display the image.

Further, it should be noted that, although in the flowchart in step 1504 is shown as after step 1503, however, the skilled in the art can understand, the step 1504 and the step 1503 may be executed in parallel, or in reverse order.

Next, at step 1505, the display processing method, according to the first adjustment parameters and the image display, processes the image to generate a first adjustment image.

More specifically, for example, in the case of brightness, the display processing method adjusts the brightness of the image based on the first adjustment parameter and the image information to generate the first adjustment image after brightness adjustment. In the case of transparency, the image display processing method adjusts the transparency of the image based on the first adjustment parameter and the image information to generate the first adjustment image after the transparency adjustment.

The processing method to adjust image processing skilled in the know, this will not elaborate.

Thereafter, in step 1506, the display processing method displays the first adjustment image.

Thus, the display processing method of the embodiment of the invention allows the user to adjust the parameters of the image displayed on the electronic device by the gesture operation which conforms to the user's habits, makes it easy to be learned by the user, makes the user operation simple, and thus greatly improve the user experiences.

In addition, further, in another embodiment of the present invention, the display processing method can not only adjust the image in the first adjustment direction, but also can adjust in the second adjustment direction.

In this case, the display processing method detects the second gesture on the electronic device operation performed by the user. Specifically, the display processing method, for example, detects the second gesture by the touch unit.

Next, the display processing method judge whether the second gesture operation satisfies the second condition. The second condition and the first condition are different. Alternatively, the second condition, the first condition, although different, but are the corresponding conditions. For the user, i.e., the first gesture operation satisfying the first condition and the second gesture operation satisfying the second condition belong to the same operation style gesture.

Specifically, in one embodiment, the display processing method determines whether the touching point's trajectory of the second gesture operation is formed by the continuous curve trajectory, which is formed by coming and going between a third sliding direction and a fourth sliding direction different from the third sliding direction. For example, the third sliding direction is the direction towards the upper side of the display unit, and the fourth sliding direction is the direction towards the lower side of the display unit. The number of the touch point may be one, or can be multiple. That is, the display processing method to determine whether the second gesture operation is similar to the so-called back and forth gesture, and the user can use a pointing (e.g., finger) to make the gesture, or can make the same gesture using a plurality of pointing objects (for example, multi-fingers).

In another embodiment, the display processing method to determine whether the first gesture operation is formed of the touch point trajectory by several times in the same sliding direction of the sliding piece in the predetermined time interval, the locus which is formed in the track. For example, the sliding direction may be an arbitrarily set direction. The number of the touch point may be one, or can be multiple. That is, the display processing method to determine whether the first gesture operation is similar to the so-called back and forth gesture, and the user can use a pointing (e.g., finger) to make the gesture, or can be make the same gesture using a plurality of pointing objects (for example, multi-fingers).

Of course, the above embodiments are only examples. One skilled in the art can understand that the display processing method of an embodiment of the present invention can set other criterion as the first condition. Alternatively, the first condition corresponding to the trajectory is formed by trajectory which conforms to the user's habit.

Next, when the second gesture operation does not satisfy the second condition, the display processing method ends. On the other hand, when the second gesture operation satisfies the second condition, the display processing method obtains the second adjustment parameter. The second adjustment parameter is used to adjust the parameters of the image in the second adjusting direction. The second adjusting direction and the first adjustment direction are opposite, i.e., for example, one of the increasing direction and the decreasing direction, here assumed to be decreasing direction. For example, in the case of brightness, the second adjustment parameter can be the luminance reduction amount.

In one embodiment, the display processing method may operate, according to the second gesture, to obtain a fixed second adjustment parameter. I.e., in the above case, for example, whatever the track of the second gesture operation is, as long as it satisfies the second condition, the display processing method obtains the same second adjustment parameter.

In another embodiment, the second adjustment parameter may be variable. Specifically, the display processing method may operate according to the second gesture, to determine the size of the second adjustment parameter. Processing is similar with that with reference to FIG. 15, which will not be described in detail here.

Similarly, on the other hand, the display processing method obtains the image information of the displayed image, and processes the image according to the second adjustment parameter to generate a second adjustment image, and display the second adjustment image.

Thereby, the display processing method of the embodiment of the invention allows the user to be able to adjust the parameters of the image displayed on the electronic device in two adjustment directions, thereby the users easily learn and master, so that the user operation is simple, which further improves the user experience.

Further, in another embodiment, the parameters of the image have an upper limit and a lower limit. The display processing method can be in operation when the first condition is met, determines whether the displayed image parameter has been reached the limit corresponding to the first adjustment parameter which is one of the upper and the lower limit. When the image parameter has reached the limit corresponding to the first adjustment parameter which is one of the upper and the lower limit, the display processing method maintains the display of the image without the adjustment.

Namely, in this embodiment, in the case of brightness, for example, the display processing method in the first gesture operation when the first condition is satisfied, judges whether the luminance value of the judgment of the image has reached the upper limit of brightness. When the brightness of the image has reached the upper limit, the display processing method maintains the display of the image without adjusting brightness.

Similarly, in the embodiment described above, the display processing method may be operated in the second gesture when the second condition is satisfied, and determines whether the parameter has reached the upper limit of the lower limit. When the parameter of the image has reached one of the upper and the lower limit, the display processing method maintains the display of the image without adjusting.

The display processing method in the second gesture operation satisfies the second condition, judging whether the brightness of the image has reached the lower limit of luminance. When the brightness of the image has reached the lower limit of luminance, and to maintain the display of the image of the display processing method without adjusting.

Thus, the display processing method of the embodiment of the invention allows the user through the gesture operation habits, within a reasonable range appropriately adjusting the parameters of the image displayed on the electronic device, thereby easily the user to learn and master, so that the user operation is simple further improve the user experience.
